since hardee's isn't on there i am going with wendy's.
This poll is hereby declared null and void since it does not include Hardee's, Sonic, Whattaburger or Jack-in-the-Box. The OP isn't by any chance from California, is he?? LOL.....
I think you may be right, OP may very well be a Claifornian, Jagger LOL. Although, technically Hardee's can be considered to be on the list b/c Carl's Jr. is essentially Hardee's west of the Mississippi. Same star logo, same exact restaurant makeup etc. just different names for the same food items is the major difference. It's like Rally's/Checker's (If anyone understands that reference). Oh, and we have JIB in CA too, must not be a fave of the thread starter LOL!
As for a relevant answer to the question, my fave fast food joint would have to be Steak N' Shake, although to my knowledge the closest one to where I live (San Diego, CA) is in Dallas, TX. So I'm shit outta luck! Had to go with "The Schnitz" as far as the poll options were concerned.
On another note, we just got Sonic in San Diego like 2 months ago and I'm pretty pumped on it!
